Three-Layer Stergen'S Vibration-Free Equation Solution

Short-term dynamic loads in shipbuilding, aircraft building and other areas of science are often caused by explosions and impacts. In general, explosion and shocking effects are caused by heavy objects falling and explosion waves. The effect of these impacts on the construction is generally due to the interaction of the design with explosion waves, falling or striking objects, and so on. Along with the foregoing, it should be noted that the problem of the oscillation of the three-layered sterile dispersion over the length of the load is often solved only in the case of classical equations and this is often the case when has led to errors. Therefore, Grigollyuk-Chulkov equation is used in this article (Harper, n.d.; Wojciechowska, 2006). Y. Xing and B. Liu, “Characteristic equations and closed-form solution for free vibrations of rectangular Mindlin plates, ” Y. Xing and B. Liu, “Closed form solutions for free vibrations of rectangular Mindlin plates, ” and other scholars all over there world were stated about the issue on their investigations and analysis.
